2 Claims. (Cl. 126-9) This invention relates to a camp stoveconstruction and has for an object to provide a stove that istransportable in compact knock-down form and which sets up to provide anefiicient and safe device that is practical to burn charcoal or campsite materials such as wood, pine cones, etc.

Another object of the invention is to provide a camp stove in' which thefire box is of large capacity, when erected, and yet may be compactlyarranged to house all of the stove elements, such as support legs,stack, warming shelves, etc.

A stillfurther object of the invention is to provide a camp stove inwhich the fire box comprises similar halves or sections that are adaptedto be nested one within the other for compactness during transportationand the hollow formed by such nested halves housing the remainingcomponents of the stove.

The invention also has for its objects to provide such means that arepositive in operation, convenient in use, easily installed in a working.position and easily disconnected therefrom, economical of manufacture,relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novelcombinations and arrangements of parts, which will more fully appear inthe course of the following description. However, the drawings merelyshow and the following description merely describes, one embodiment ofthe present invention, which is given by way of illustration or exampleonly.

In the drawings, like reference characters designate similar parts inthe several views.

Fig. 2 is an enlarged vertical and fragmentary sectiona1 view as takenon line 2-2 of Fig. 1.

Fig. 3 is a fragmentary sectional view as taken on line 3-3 of Fig. 1. i

Fig. 4 is a rear end elevational view of said stove in knock-downcondition.

Fig. 5 is a similar view of the opposite end.

Fig. 6 is a side elevational view of the stove as in Figs. 4 and 5.

Fig. 7 is an enlarged and broken longitudinal sectional view as taken online 7--7 of Fig. 4.

Fig. 8 is a similarly enlarged cross-sectional view as taken on line 8-8of Fig. 6 with certain parts removed.

The camp stove that is iluustrated comprises, generally, a fire box 10provided with a flue o1- stack 11 and supported on a set of legs 12, anda pair of warming shelves 13 attached to the opposite sides of the firebox. The present stove structure includes a closure member 14 used inthe knock-down arrangement of the parts to unify the compactly arrangedparts for ready handling, storage, and transportation.

The fire box, in this instance, comprises two similar halves l5 and 16,respectively upper and lower, the same being preferably formed of sheetsteel and so proportioned that the lower half 16 is adapted to fit intothe Fee upper half 15, as illustrated in Figs. 7 and 8. Thus, while bothhalves 15 and 16 are rectilinear in form, the upper half 15 is somewhatlonger, wider and higher than the lower half 16.

The upper half 15 of the fire box is formed to have a top 17, sides 18,and a back 19, that comprise immovable walls, and a front wall or door20 that is connected to the forward end of the top 17 by a hinge 21.Thus, said front wall 20 is capable of being swung open on its hinge togive access to the interior of the upper part of the fire box. Anadjustable draft control 22 is provided on the door 20 and may beadjusted, as desired, while the door remains closed. The lower edges ofthe side walls 18 are provided with outturned flanges 23, and the loweredge of the back wall 19 is provided with a similar flange 24.

The lower half 16 of said fire box is formed to have a bottom 17a, sides25, and a back 26, that comprise immovable walls, and a front wall ordoor 27 that is connected to the'forward end of the bottom 17a by ahinge 28. Said front wall 27 is capable of being swung open on its hingeto give access to the interior of the lower part of the fire box. Thus,it will be seen that the two doors 20 and 27, when open, provide a fullyopen front on the fire box. An adjustable draft control 29 is providedon door 27, the same being similar to draft control 22, and isindependently operable. The upper edges of the side walls 25 areprovided with outturned flanges 30 similar to and matching the flanges23 of the upper half of the fire box, and the upper edge of the backwall 26 is provided with a flange 31 that is wider than flange '24 andmatches therewith, as shown in Fig. 3.

Bolts or the like 32 are used to connect the fire box halves, in themanner shown in Fig. 1, so that top 17 constitutes the stove top. Inpractice, it is preferred to reinforce both the top 17 and bottom 17awith transverse members 33 that are shown as sheet metal members weldedto the respective walls. The same minimize buckling of the fire boxwalls under expansion and contraction induced by heating and cooling.

The upper half 15 is preferably the larger half, because the same, onits top 17, is provided with an outer collar 34 which, ordinarily, wouldinterfere with nesting within the other fire box half. As shown in Figs.1 and 3, said collar orflange 34 is placed near the back of the fire boxand serves to receive the flue or stack 11. The

latter, in this instance, is shown as two separably connected tubes 35and 36, the former connecting to flange 34 and the latter to the upperend of the former. A damper control37 may be provided in one of the fluetubes, in this case the lower one 35.

From the above construction, it will be seen that adjustment of thedraft and damper controls may be readi ly effected to produce a greateror lesser movement of air across or through a fire in the fire box. Suchcontrol may be effected with the fire box otherwise closed. Only whenstoking is it necessary to open the front doors 20 and/ or 27.

The set of legs 12 is shown as comprising four legs 38 in cornerarrangement and connected to the lower half 16 of the fire box as bysockets 39 afiixed to the inner faces of the side walls 25 of said lowerhalf. Said sockets are placed inside the half 16 so as not to interferewith proper nesting of the halves. Each leg 38 is provided with a stopflange 40 near its upper end, the same limiting the extent of engagementof said end in its socket. The lower ends of the legs are formed so theyspread to provide a stable base for the stove.

The pair of warming shelves 13 is shown as similar rectangular shelfmembers 41 that may be variously formed and which, as shown, comprise aframe 42 surrounding a perforated or comparable support top 43.

Said frame and top are generally flat and along one side thereof thereis provided an angularly bent lug or the like 44 at each end,substantially as shown. The side walls 18 of the fire box half15 areeach provided with a pair of sockets 45 that receive lugs 44and,"therefore, are spaced according to the longitudinal spacing of saidlugs. Said sockets are so located that the warming shelves are indesired flush or nearly'flu'sh' association with the stove top 17 whenthe lugs 44 are entered thereinto.

When the fire box halves 15 and 16 are nested, the flanges 23 and 30(Fig. 8) engage to constitute a pair of relatively strong longitudinalflanges, and flange's'24 and 3 1 (Fig. 7) engage to constitute arelatively strong transverse flange. Since the sockets 39 are on theinner faces of the side of the inner half 16, 'said halves nest onewithin the other, as in Figs. 7 and 8.

The flue sections 35 and 36, the legs 38, and the warming shelves 41,are made of a length to fit within the inner half 16. The arrangementmay vary, the drawings (Figs. 7 and 8) showing a suggested arrangementof said parts within the inner half 16. 1

When arranged as above described, the open top the nested halves may beclosed by member 14 which is provided with opposite longitudinal flanges46 which engage with the superposed flanges 23 and 30 on each side, withan end flange 47 that engages and is limited by the door 20 of the outerhalf 15, and a spring catch 48 on the end opposite to flange 47 andadapted to have spring retention with flange 31 of the inner half 16.Said closure 14 is slid into place and, when retained by the catch 48,renders the components unitary and compact. Since the flanges 46 areinwardly bent, the closure retains its position against outwarddisplacement and, since the door 20 is hinged to swing outwardly, theflange 47 prevents such movement.

The compact unit above provided may be easily handled and facility ofhandling is improved by providing one side wall 18 with a folding handle49.

While the foregoing has illustrated and described what is nowcontemplated to be the best mode of carrying out the invention, theconstruction is, of course, subject to modification without departingfrom the spirit and scope of the invention. It is, therefore, notdesired to restrict the invention to the particular form of constructionillustrated and described, but to cover all modifications that may fallwithin the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. A knock-down camp stove, comprising a fire box formed of upper andlower halves of rectilinear form, one being smaller than the other,whereby the two halves are adapted to nest with the smaller inside thelarger half, each half being provided with longitudinal outturnedflanges along the side edges thereof and with flanges along one endedge, said flanges being respec tively superposed and engaged with eachother when the halves are nested and when the same are arranged with thehalves in mutually inverted relation to form a fire box space, saidnested 'halves" being open within the flange-provided edges thereof, anda closure plate across the opening in the inner half and extending overthe superposed flanges when the halves are nested, a longitudinal inturned flange along each side edge of the closure plate, said plate beingadapted to he slid over said opening, from the ends of the nested halvesthat have the end flanges, with the inturned flanges engaged beneath theside flanges of said larger half.

2. A camp stove according to claim 1 in which the closure plate isprovided with a spring catch at the end thereof that is disposed overthe end flanges of the nested halves, said catch engaging said endflanges to limit the slid-on position of the closure plate.
